Re: /boot on RAID1 with fedora21

Hi,

    In the past, it's had a tendency to always put /boot only on
    /dev/sda, meaning if the first disk dies, the system becomes unable
    to boot.

I have a software RAID for /boot working on CentOS 6 servers at work, so
I would be very surprised if it could not also be done in Fedora. It
does require you to be somewhat familiar with RAID and disk partitioning
concepts to make it work.

It appears to work, but...

Also, you have to look out for the boot block install (what
"grub2-install" puts on the disk). It doesn't do you any good to have a
RAID for /boot if the boot block isn't also present on both disks.

Installing to /dev/md0 has also been a problem. Is the procedure to install /dev/sda and /dev/sdb, then switch the boot order in the BIOS when sda dies?

Often times when it dies, it won't automatically switch to another disk, it seems.

Thanks,
Alex
